Qhov cuam tshuam ntawm Unbalanced TsavRotorsntawm Motor Quality
Dab tsi yog qhov cuam tshuam ntawmlub rotorimbalance ntawm lub cev muaj zog zoo?Tus editor yuav txheeb xyuas qhov teeb meem vibration thiab suab nrov tshwm sim los ntawmlub rotormechanical imbalance.
Yog vim li cas rau unbalanced vibration ntawm lub rotor: residual imbalance thaum lub sij hawm tsim khoom, ntau adhesion ntawm hmoov av generated thaum lub sij hawm ntev ua hauj lwm, ncej dabtsi yog khoov los ntawm thermal stress thaum lub sij hawm ua hauj lwm, unbalance load tshwm sim los ntawm thermal displacement ntawm rotor accessories, deformation los yog eccentricity los ntawm centrifugal quab yuam. ntawm cov khoom siv rotor, ncej dabtsi yog khoov los ntawm sab nraud quab yuam (cov siv tsis zoo, lub zog, cov pob qij txha ncaj, thiab lwm yam), ncej dabtsi yog khoov los ntawm cov khoom siv tsis zoo (qhov tseeb ntawm lub tog raj kheej lossis lub xauv), lossis cov kabmob sab hauv deformation.
Yuav ua li cas suppresslub rotorimbalance: tswj nws nyob rau hauv qhov kev tso cai tsis txaus, txhim kho qhov nruj nruj ntawm cov ncej thiab cov tub ntxhais hlau, thiab txhim kho tus qauv tsim rau cov heterogeneity ntawm thermal expansion.Kev txhim kho lub zog tsim los yog kev sib dhos, kev hloov kho ntawm lub zog ntawm lub zog tsim, kev hloov ntawm hom ncej txuas, kho qhov sib txuas ncaj nraim mus rau qhov chaw, tiv thaiv kev sib txawv ntawm cov kabmob kawg lub ntsej muag thiab cov ncej txuas los yog xauv cov txiv ntoo.
Qhov ua rau muaj qhov txawv txav thiab lub suab nrov hauv cov kabmob muaj xws li kev puas tsuaj rau cov kabmob, kev co tsis zoo nyob rau hauv cov kev taw qhia axial ntawm cov bearings, excitation ntawm lub vibration system tsim los ntawm axial caij nplooj ntoos hlav tas li thiab rotor loj;Tsis zoo lubrication thiab bearing clearance tshwm sim los ntawm cylindrical dov bearings los yog loj txoj kab uas hla high-speed pob bearings.
Hloov cov bearings: Siv qhov tsim nyog axial caij nplooj ntoos hlav preload los hloov cov kabmob tshem tawm, xaiv cov roj roj lossis roj nrog kev ua haujlwm kub qis, thiab txo qhov seem seem (ua tib zoo saib xyuas qhov kub thiab txias).
Rotordynamic tshuav nyiaj li cas kho txoj kev: Tom qab lub dynamic tshuav nyiaj li cas ntsuas ntawm lublub rotorntawm lub tshuab dynamic tshuav nyiaj li cas, lub rotor tuaj yeem sib npaug thiab ua tiav siv txoj kev hnyav thiab kev tshem tawm qhov hnyav raws li xav tau.Cov txheej txheem hu ua qhov hnyav yog hais txog kev teeb tsa ntawm kev kho qhov hnyav hauv qhov sib txawv ntawm qhov tsis sib xws.Cov kev siv feem ntau muaj xws li vuam, soldering, riveting, screwing, thiab hnyav blocks.Txoj kev tshem tawm qhov hnyav yuav tshem tawm qee qhov hnyav ntawm qhov tsis sib npaug.Cov kev siv feem ntau muaj xws li tho txawv, drilling, chiseling, milling, sib tsoo, thiab lwm yam.
